Filed: 1968-05-14
Abstract: 1,175,336. Protective arrangements. ARDCO Inc. 14 May, 1968, No. 22882/68. Heading H2K. [Also in Divisions F4 and H1] A glass panel 12 having a heating element 28 thereon is protected by a switching device 10 having a first means 50 for causing the closing of the device 10 when power is applied and second means 42 responsive to the load current to maintain the device closed so that interruption of the load current, e.g. due to breakage of the panel causes the opening of the switch device. As shown, the device 10 is a thermal relay having three fixed contacts 46 ... 48 and a moving contact 44 on a bi-metallic strip 42 heated by a heating resistor 50 when power is applied. The bi-metallic strip then deflects so that the contact 44 is brought into engagement with the contact 48. This completes the circuit for the panel heater 28 and disconnects the resistor 50, the relay being maintained closed by the heating of the bi-metallic strip 42 by the load current flowing through it. When the load current is interrupted, the bi-metallic strip 42 cools opening contacts 44, 48 and closing contacts 44, 47 so that the bi-metallic strip is heated by a resistor 52 and remains in a central position to prevent repeated interruption and restoration of the supply to the element 28. In a modified arrangement, Fig. 6 (not shown), the resistor 52 is connected between fixed contacts 46, 47. In other arrangements, Figs. 2, 4 and 5 (not shown), the thermal relay has two fixed contacts and the first means is a heating resistor connected across those contacts. Fig. 3 (not shown), illustrates an arrangement in which the switching device is an electromagnetic relay having a coil connected across its contact and a coil connected in series with its contacts.

[Also in Divisions G1 and G2] In a system for photo-electrically analysing a schlieren image, the line of the image currently being investigated is indicated by a bright line superimposed on a television picture of the image. The image is viewed by a television camera 100, Fig, 41, and the video signal is applied firstly for display on a cathode-ray oscilloscope 108 and secondly to a monitor 122. The circuit 105 selects the frame sync. pulse and applies it to an adjustable delay 109. The delayed sync. pulse is used to trigger oscilloscope 108 and also to initiate the production of a rectangular pulse R of one line duration. The pulse R is applied via a trigger circuit 123 to brighten a line on the monitor 122 corresponding to the line of the schlieren image being represented on the oscilloscope 108. In a modification, Fig. 44 (not shown), the frame sync. pulse is not itself used to trigger oscilloscope 108 and initiate pulse R, but instead gates a particular line sync. pulse to perform these functions. In this way oscilloscope 108 always displays a complete line. The gated line pulse may be delayed so that the beginning of the traces on oscilloscope 108 corresponds to the edge of the schlieren image and not the edge of the raster of camera tube 100.

A lamp failure alarm device of the type wherein the coil of an electromagnetic relay is included in the circuit to be supervised and operates an alarm on de-energization is protected against harm due to a short-circuit in the supervised circuit by the provision of a thermoresponsive member situated in proximity to the coil and arranged to close the alarm circuit and open the supervised circuit when the heat generated by the coil reaches a pre-determined amount. In the embodiment described the lamp to be supervised, in series with a normally closed contact under control of a bimetallic strip, is connected across the armature contacts of a buzzer, the coil of which has the bimetallic strip in close proximity. Thus the lamp current maintains the buzzer coil energized and the contacts open, and the lamp is, of course, illuminated. If the lamp fails the circuit across the buzzer contacts is opened and the buzzer operates to sound an alarm; also if the lamp is short-circuited the buzzer coil heats up, opens the bimetallic strip contact and again opens the circuit across the buzzer points and allows the alarm to sound.
